Question

Which equation can be used to solve for b?

Answer 1

b = (8)tan(30o)

Explanation:

Answer 2

The first one

Explanation:

Using the tangent ratio in the right triangle

tan30° =
`(opposite)/(adjacent)` =
`(AC)/(BC)` =
`(b)/(8)`

Multiply both sides by 8

8 × tan30° = b, that is

b = 8tan30°
